Standby mode
If frost protection is activated, the controller will go into ”Standby mode” when the
running mode switches to ”Off”. The “Standby mode” will control the heating output
to maintain a constant settable temperature at the frost protection sensor “Setpoint
Standby mode”.
Electric heating
Control
The heating is controlled using the analogue output and/or signal for start heating
or step controller to control 1..4 digital output steps.
Overheat protection
On Activate of the digital input “Overheated electric heater” the unit will be shut
down, either according to the stop sequence described in section Start/stop of unit
or as an emergency shutdown. The unit will restart after the alarm has been
acknowledged and “Electric heating is overheated” has reset.
Flow switch
Note that Activate of the input signal “Flow switch” will also stop the unit. Note: It is
important that the high temperature thermostat is hardwired to disconnect the
power to the heater. That is to ensure that the heating is shut down when the
thermostat is activated even if the Access controller should be faulty.
Fast stop on overheating
If the function "Fast stop on overheating" is active, the fans will be immediately
stopped when there is an overheating alarm, regardless of the set cool-down time.
Step controller heating
Activate: By configuring the electrical heater the step switch will be activated in the menu.
